This power window regulator makes a great replacement and has good cost savings over a dealer unit.

Please Note: This window regulator is a high quality aftermarket part that meets or exceeds the performance of the original.  It has been subjected to extensive testing and quality control standards.  That is why we offer this regulator with our superior warranty!


  • This repair is easier than you may think. You'll find our installation videos helpful. In our experience removing and replacing the door panel is the most involved step in the repair. On most vehicles this only requires removing a few screws and push-in clips.
  • You'll get a great feeling of accomplishment after you complete this repair knowing you saved money, and you didn't have to give up your car for a day at the repair shop. Your passengers and other drivers will be amazed.

Fit guaranteed

  • 1A Auto will refund you with no hassle, if this window regulator does not fit the application stated.
    •  This regulator will install just as your original does. Save time and money.


  • Be confident this part will work right. Every regulator is tested after assembly to make sure all mechanisms are working correctly.
  • It is important that your new regulator works for a long period of time. The design of this regulator is tested to withstand 10,000 cycles. That is enough to raise and lower your window 3 times per day for 9 years.


  • Windows that don't work can be frustrating. They can also hurt your vehicles value. An inoperable window could mean $200-$500 discounted off a dealer trade value or asking price.
  • Some shops and dealers charge more for parts and repairs when they think you don't know what is involved. Now you can get the value you deserve. Knowing what this repair entails can be the difference between the value of doing it yourself, or the pain of a costly repair bill.

Impala RR window regulator
Part fit like a glove. follow youtube instructions and it will take a 1/2 hr or less of your time. Zero problems. I'd bet the dealership would have charged me over $75 in labor for a job that took 20minutes. I'm the least mechanically inclined in my family and I didn't have to call the mechanic family experts for help!! The door latch cable is tricky to get in/out of clip. Push ears in and pull through, then just push back through once you re assemble. I kept trying to pull up at first to get it out of tab.

Thought they sent me the wrong part at 1st.
When I 1st unpacked it I thought they had sent me a drivers side unit instead of the passenger side I needed because the motor appeared to be oriented 180 degrees out from the original I had just removed from my car. I later figured out that they had changed the design slightly from the original and that it was indeed the correct part. Works like a champ! Will buy from them again!

Great product easy install
I had my factory window regulator fail and was in need of a replacement part. Searched at my local auto parts store and was in shock of the extreme price of the simple part. Stumbled upon the 1 A auto website and just for a giggle searched their site for the part. I ordered it immediately. The price was a fraction of the auto part store and the how to video made the installation a breeze. Will definitely be a repeat visitor in the future.

Most satisfied
I was impressed by the savings, quick order delivery, customer service, how to videos, and the window regular price at $44.95. I priced this item at Auto Zone and Merle's Auto only to be told it would be $240.00 and more. Window regulator fits and works great in my Impala. My sincere thanks and new loyal customer...Alex
